In the past LT was a higher up model than the LS. Most recent LS/LT models I recall were the s10 blazer, LT was the leather and LS was the cloth usually. At least they are trying to give some more options so they all don't look alike. All the SUV basher like telling everyone they should buy cars and if they would add a few more optins to the cars they might sell a bit more. Factory tinted rear windows would help out a lot on cars in the summer days, My S10 can freeze you on the lowest setting while an Impala you sweat with the AC on high, I think it due to the greenhouse like windows.
